This is a Tamiya 33T Brushed 540 Motor, intended for use with 1/14 scale R/C Tractor Truck models. It prevents speed loss in the top gear of the 3-speed transmission, while allowing longer runs and easier maintenance. Low turn motor provides high torque, which gives the model more realistic and effective running in its top gear. This motor comes equipped with ball bearings and has lower power consumption. Lower power consumption means longer driving times.
